Sandy Fox is an American voice actress with an extensive career spanning anime, animation, and video games, recognized for her distinctive high-pitched and youthful vocal performances. Born Sandra Marie Kessler on July 13, 1963, in Monroeville, Pennsylvania, she began her entertainment career in live performance, working for the Walt Disney Company in Orlando and singing with a 1920s-themed jazz band for eleven years. In 1991, she was cast as the live-action portrayer and voice of Betty Boop for Universal Studios, a role she would hold for over three decades, voicing the character for promotional activities, theme park attractions, and international commercials. This move to Los Angeles for the Betty Boop role led her to pursue voice acting professionally after taking a workshop with director Sue Blu.

Fox's entry into anime voice acting began with some of the medium's most influential titles. Her first major anime roles included Kiyoko in the Animaze dub of the seminal film Akira and Lady Aska in the Magic Knight Rayearth series, for which she also rewrote lyrics and performed theme songs. These early roles established her as a go-to talent for anime dubbing produced in Los Angeles.

Throughout the 2000s, Fox became a prolific voice in the industry, often collaborating with studios like Bang Zoom! Entertainment. She is particularly known for her ability to voice cute, energetic, or childlike characters. This talent is evident in some of her most iconic roles: she voiced the adorable persocom Sumomo in Chobits; the childlike Flonne in the Disgaea video game and anime series; the sentant tank units Tachikoma in Ghost in the Shell: Stand Alone Complex and its accompanying Tachikomatic Days shorts; and the dual roles of Momiji and Mina in the Naruto series. Her performance as the title character in Ground Defense Force! Mao-chan was highlighted by Anime News Network, which noted her "cutesy 'little girl' voice" as a perfect fit for the role.

Her filmography from this period is extensive and includes many of the roles specified in the query. She voiced Este in Shinzo, Risky in Omishi Magical Theater Risky Safety, Monica Gabriel in Heat Guy J, Amefuriko in the OVA series Karas, Marie in Haré+Guu Deluxe, Kurumi the Hamster in Angel Tales, T-AI in Transformers: Robots in Disguise, Meeko in Catnapped! The Movie, and Sakura in Ninja Cadets. She also voiced the character Pyocola Analogue III, also known as Piyoko, in the Digi Charat franchise, including the series Leave it to Piyoko!.

In 2014, Fox was announced for a role that would connect her to one of anime's most beloved franchises for a new generation of fans. She was cast as the English voice of Chibiusa, also known as Sailor Chibi Moon and Black Lady, in the Viz Media redub of the original Sailor Moon anime and the new Sailor Moon Crystal series. She has since reprised this role in subsequent films, including Pretty Guardian Sailor Moon Eternal and Sailor Moon Cosmos. Her other notable later credits include Courtney in Pokémon Generations and Eddelrittuo in Aldnoah.Zero.

Beyond anime, Fox's voice is widely recognized in video games, with credits including Mistral and A-20 in the.hack series, Peashy in Hyperdimension Neptunia, and Marona in Phantom Brave. She has also contributed voices to Western animated series such as The Simpsons, King of the Hill, Futurama, Hi Hi Puffy AmiYumi, and As Told by Ginger.

Fox is married to fellow voice actor Lex Lang, and together they co-founded the non-profit Love Planet Foundation, which creates educational materials for children on environmental and social issues, as well as a bottled water company.
